PVA China polyvinyl alcohol 0588,0599,

PVA is usually processed in the form of aqueous solution. Since the solution is slightly acidic (pH 5~7), vessel

should be made of materials, which will not contaminate the solution with corrosive material or rusts. Stainless

steel vessel, enameled containers or polyester tanks are recommended.

The specific gravity of PVA is ranging from 1.26 to 1.31, which is heavier than that of water. Low agitation speed

or unfavorable agitating condition sometimes causes coarse particles to precipitate and to block the outlet of

the dissolving tank. Hence, a flush valve or tank valve is recommended to be installed in the bottom of the vessel to prevent the particles from blocking the discharge line.

Textile Warp Sizing

The high film strength, flexibility, abrasion resistance, and good adhesion of PVA combined with its water solubility make PVA an efficient warp size for spun and filament yarn.The advantages of HOPEWAY PVA as a sizing agent

are listed as following:
